Meanwhile, though true-blue 1D fans follow the ups and downs of the lads' love lives with eagle eyes, the 19-year-old Styles says he can't worry about other people's opinions when it comes to his relationships. And that includes the opinion of a particular ex.

"It would be hypocritical for me to say she couldn't do it because everybody writes songs based on personal experience," Styles told Us Weekly in a recent interview, referring to Taylor Swift and her famed penchant for breakup tunes. "At least she's a great songwriter!"

As for trying to have a life when the world is watching, Styles admits it's incredibly difficult.

"I think relationships are hard enough, so I think you have to completely ignore everything from outside," he said. "When you're in the opening stages of a relationship as it is, you're still under the pressure of getting to know everything about a person. If you have a lot of people from outside telling you what it is and they don't even know you, telling you what your relationship is, that's weird. So I think you sort of have to block it out and just have the relationship rather than think 'we're having this relationship play out on magazine covers.'"
